HEAVY DUTY/VEHICLE BRACKET
ADJUSTMENT
If a bracket is not properly adjusted, the bracket may be
damaged, and the extinguisher may be damaged or lost.
Readjustment of a bracket may be required periodically
due to physical abuse of the bracket and/or the aging of the
neoprene pads. This procedure covers both initial adjustment
and later re-adjustment of heavy duty type brackets.
1. Place the extinguisher in the bracket as shown, making
sure that it is firmly in the bracket base.
2. Hold the clamp arm level as you place it around the
extinguisher. Arrange the arm, the extinguisher and the
hose for the best fit.
3. Swing the handle open as shown. The handles on the two
larger brackets (for the Model 20 and 30 extinguishers)
have mechanical stops which prevent the handles from
being opened too far. The smallest bracket (for the Model
10 extinguishers) does not have this stop. Open the
handle only as wide as is shown in the figure. (The Model
10 bracket has a small mark on the handle to serve as a
reference point.)
4. Adjust the length of the T-bolt so that it just fits into
the notches on the bracket handle when the handle is
properly opened. Be certain that the T-bolt retaining nut is
properly positioned as indicated in the figure. (The T-bolt
length is adjusted by turning it.)
5. Place the T-bolt in the handle notches. Check carefully
to see the T-bolt is properly seated in the handle and is
square to the bracket back. If necessary, reposition the
bracket arm to obtain a good square fit.
6. With the T-bolt properly seated in the handle notches,
carefully close the handle, clamping the extinguisher into
the bracket. Take care to avoid being pinched as the
handle snaps closed.
7. Check the adjustment. If the extinguisher or the bracket
arm has play in them, or if the bracket handle opens
and closes too easily, the bracket needs tightening. If
the tension makes it difficult to open or close the bracket
handle, the bracket is too tight and should be loosened.
Remember that either too tight or loose a bracket may
cause damage. Maintain a snug, but not over-tight
bracket.
